Why must there be an explanation? Why do we as humans feel the need to have an explanation for something even if it's completely false?

Throughout history societies use stories and other made up bullshit to explain why things happen. I think we as a race are unable to grasp the possible conclusion that there is no explanation, we don't know and may never know how we got here, and we could very well be accidents. So, we make shit up so we can sleep at night.

So long as you include evolution with creationism in this statement I completely agree.
